we have a Bes Express server set up on a Windows 2008 server. I can access the web admin console from my PC in Internet Explorer 9. My other colleague can from IE 11. When I get to the page, I see a 'Continue to this website' (not recommended).
The link is this: https://besexpress.uk.fc.local:3443/webconsole/login
One of my colleagues who is on the same network as me, is unable to access this page. He gets a page cannot be displayed from his IE 11 instead of what i see.
All firewalls are off on server and PC's. Could it be certificates related on his PC? Or even security update?
